0.2" pitch side entry PCB mount screwless terminal block 2 ~ 24
poles
Description:
Screwless PCB terminal blocks are often used where high volume or
quick assembly is needed. No tools are required to make connection
if solid wire or stranded with ferrules is used. The wire will open
the gate and be secured just by pushing it in. Some types have
actuators or a tool slot which allow stranded wires to be used
without ferrules.
These terminal blocks have spring terminals that automatically grip
inserted wires and release when their levers are pressed with a
fingernail or small object, enabling easy, temporary connections to
a PCB.
It is possible to reconfigure these terminal blocks by combining
them to make larger ones or to removing segments to make them
shorter. To combine two terminal blocks, you must first pry off the
end cap from one. With the end cap removed, there is nothing to
hold the last lever in place, so be careful not to lose it! Once
the end cap is removed, you can line up the newly exposed prongs
with the holes on the side of another terminal block and press them
together.
Applications:
The terminal blocks are used in almost all electric appliances that
need 240-volt power supply.

Terminal blocks selection guide:
How do we connect two wires? By stripping the insulation at the
ends and twisting them together? Yes, it works. But, is it safe? We
can apply insulation tape over the joint or use a wire connector.
But what if there are a number wires that need to be
joint/connected near each other? Or, what if multiple outgoing
wires are to be connected to a single incoming wire? Then this
method will neither be safe nor be convenient anymore. Here we use
terminal blocks.
But there are so many kinds of terminal blocks. How can we choose
the right one?
The difference between blocks can lead to problems if an incorrect
type is used or if it is not connected properly. Follow the advice
below:
• Look at the electrical equipment you are working on to see what
type of connection it requires; normally you will have either a
screw-in or plug-in connection. Screw-in wires are placed inside
the terminal block and screwed into position, and they are most
common for equipment that does not require high voltage protection.
A variation on the screw-in connection is one held in place by a
spring mechanism. This connector can reduce the time spent on the
job because you simply clip it into place instead of removing and
replacing the screw.
A plug-in connection has a male terminal at the end of the wire.
This terminal is connected to the female port on the terminal block
and forms a secure connection. Plug-in blocks are commonly used in
the fuse boxes of automobiles.
• Once you know the type of connection that is required, you need to
find a terminal block that fits the rest of your requirements.
Consider what space you have for the connection and how many wires
need to be connected. Terminal blocks are supplied in a variety of
shapes and sizes, so you should be able to find one that suits your
needs.
• Choose the correct rating. 3A, 5A, 15A, or 30A terminal blocks are
widely available, and you'll want to buy the one that meets the
highest current level that it will conduct in order to allow the
most powerful piece of equipment to function.
